Note!
The shielding on the inverter side has to be applied according to the manufacturer‘s connection dia-
gram.
Explanation:
► Connecting the shielding to the ground prevents interference of any kind. However, the shielding
may only be connected to the ground on one side of the data bus!
Connect the inverters together
•
Wiring using a 3-pin cable with a terminal block connector.
•
Where to connect: RR485 socket in the inverter.
Procedure:
1. Insert the terminal block connector into the first inverter‘s RS485 socket.
2. Insert the other terminal block connector into the second inverter‘s RS485 socket
3. Connect the other inverters to each other in the same way.
4. Insert the terminal block connector into the Solar-Log™ RS485 socket
Assign the communication address
•
Recommendation: Continuous numbering starting with 1.
•
Address range: 1 - 125.
•
Setting: Using the inverter‘s operating display.
•
Procedure: Start according to the inverter‘s instructions.
